Hello,
You can get your ob or midwife's opinion, but I'd suggest a shower only after rupture of membranes.
Best regards,

well from wat i have gathered it is fine to take baths, just not with any high temperatured water. im 32 and have to take baths due to i cant stand anymore. and if you have seen the movie knocked up notice she is in the tub whilst in labor before she gets to the hospital, it should be definately ok, just ask your doctor for more info
